Co-translational protein targeting facilitates centrosomal recruitment of PCNT during centrosome maturation in vertebrates. [PDF]
, 2017 As microtubule-organizing centers of animal cells, centrosomes guide the formation of the bipolar spindle that segregates chromosomes during mitosis.

Random intermittent search and the tug-of-war model of motor-driven transport [PDF]
, 2010 We formulate the tug-of-war model of microtubule cargo transport by multiple molecular motors as an intermittent random search for a hidden target. A motor-complex consisting of multiple molecular motors with opposing directional preference is modeled ...

Nuclear-localized subtype of end-binding 1 protein regulates spindle organization in Arabidopsis [PDF]
, 2010 End-binding 1 (EB1) proteins are evolutionarily conserved plus-end-tracking proteins that localize to growing microtubule plus ends where they regulate microtubule dynamics and interactions with intracellular targets.

FEBS Open Bio, 2021 Motile kinesins are motor proteins that translocate along microtubules as they hydrolyze ATP. They share a conserved motor domain which harbors both ATPase and microtubule‐binding activities.

Microtubule‐Associated‐Protein MAP1 is not Implicated in the Polymerization of Microtubules [PDF]
European Journal of Biochemistry, 1980 Addition of DNA to microtubule protein solutions results in a decrease of the amount of the high‐molecular‐weight microtubule‐associated proteins (MAP1 and MAP2) available for polymerization. Complete removal of MAP1 from microtubules requires lower concentrations of DNA compared to MAP2.

CLASP promotes microtubule bundling in metaphase spindle independently of Ase1/PRC1 in fission yeast
Biology Open, 2019 Microtubules in the mitotic spindle are organised by microtubule-associated proteins. In the late stage of mitosis, spindle microtubules are robustly organised through bundling by the antiparallel microtubule bundler Ase1/PRC1. In early mitosis, however,

Identification of microtubule-associated proteins in the centrosome, spindle, and kinetochore of the early Drosophila embryo. [PDF]
, 1989 We have developed affinity chromatography methods for the isolation of microtubule-associated proteins (MAPs) from soluble cytoplasmic extracts and have used them to analyze the cytoskeleton of the early Drosophila embryo.

Polymorphic Dynamics of Microtubules [PDF]
arXiv, 2010 Starting from the hypothesis that the tubulin dimer is a conformationally bistable molecule - fluctuating between a curved and a straight configuration at room temperature - we develop a model for polymorphic dynamics of the microtubule lattice. We show that tubulin bistability consistently explains unusual dynamic fluctuations, the apparent length ...

Motor protein transport along inhomogeneous microtubules [PDF]
arXiv, 2020 Many cellular processes rely on the cell's ability to transport material to and from the nucleus. Networks consisting of many microtubules and actin filaments are key to this transport. Recently, the inhibition of intracellular transport has been implicated in neurodegenerative diseases such as Alzheimer's disease and Amyotrophic Lateral Sclerosis (ALS)

N-Propionylmannosamine stimulates axonal elongation in a murine model of sciatic nerve injury
Neural Regeneration Research, 2015 Increasing evidence indicates that sialic acid plays an important role during nerve regeneration. Sialic acids can be modified in vitro as well as in vivo using metabolic oligosaccharide engineering of the N-acyl side chain.
